It sure is a bug. I am getting curious as to what program is adding it 
automatically. The only thing that makes sense to me is that it is not 
getting realized by feedback from the kernel. hdd=ide-scsi parameter. 
Since it seems to see a new device. It names it /dev/hdd (via symlink 
/dev/cdrom? - so it adds this "new device" to the /etc/fstab file.

This is a guess. I'll try to remove the /dev/cdrom2 link and boot into 
the stock kernel for psyche to test the theory. With the latest kernel 
for phoebe3, I get this device added to my kernel.

Also, If I added an entry for /dev/scd0 to my fstab file and tried to 
use the disk management tool. It would not show up in the tool until the 
next reboot. I cannot remember if I tried mount on the command line. But 
I did try mounting /dev/hdd from the command line and got the same error 
mentioned earlier.

It is an entertaining problem though. Thanks for suggesting the adding 
entry, then rebooting the machine. Othrwise, I'd still be confounded by 
the problem.
